Cast
Batman Bruce Wayne Kevin Conroy
Batman/Nightwing/Dick Grayson it's a tough call either bring back Lorren Lester or if he doesn't want to do it Will Friede.
Alfred Timothy DaltonI just can imagine him saying the bad ass lines Alfred said in the comics

outside of that I'm not sure but 1 little thing i'd like since the comics are alluding to both Bruce and Dick getting a ton more action I'd like it if in the animated series Dick had some fun nothing to graphic obviously but a scene with babs in bed next to him or something of that sort would be nice.

just my 2 cents

I've decided for fun I'm going to try and create a fanmade animated intro based on what is already out there (i can edit clips together but draw not so much) it's gonna be tough but I'm gonna try.
